MICHIGAN, ASSIGNOR OF ONE-HALF TO FRANK H. BESSENGER., OF DETROIT,MCHIGAN.

ARMORYE'ORLPNEUMATIC TIRES.

To all whom, ifm/ay concern:

Be it known that l, ALANsoN A. MOORE, a citizen of the United States ofAmerica, resid- .ing at Detroit, in thecounty of Wayne and State ofMichigan, have invented certain new and useful Improvements in Armor forPneumatic Tires, of-which the following is a speciication, referencebeing had therein to the accompanying drawings.

'This invention relates` to an improved armor for pneumatic tires; andits object is to provide a inetal covering or sheath for the tire whichis so constructed as to practically obviate the possibility of the tirebecoming punctured and which is so strongly constructed and attached asto positively hold the tire from bursting, yet does iiot'interfere withits resiliency.

It is also an object of the invention to provide means fordetachablyseeuring the arinor in place so that it may be quickly andeasily detached to repair the tire or may be entirely .re`rnovcd,` ifdesired, aiul to provide means` foi' adjusting each individual niciiiherforming the armor, so as to niake a smooth tread.

To this end the invention consists in forming the armor of amultiplicity of inde endent chains peculiarly formed and c osely wovenand extending transversely of the tire, each chain being attached ateach end by adj usting-screws to the wheel-rim or to detaehable bandssecured' thereto; and the invention further consists in providinv thedevice with certain other new and usefiilfeatures and the advantages ofthe partir ular arrangement, construction, and combination of parts, all

f as hereinafter more fully described, and sho wn in the accompanyingdrawings, in which- Figure 1 is iside elf"` ati( fi of an autel-.io-

E, is e plan view ofa portion of the tire, .iowlng theproteetiiig strip and plates with oneof the chains in place thereon. Figs. 4, 5, and 6 are sections similarto that shown in Fig. 2, showing modiiied iorms of fastening mean. forthe arinor.

Fig. 7 is a plan view o` a portion' of the wheelrini shown in Fig. 6,and Fig. l is an enlarged detail view of onel of the cha ins.

As shown in the drawings, 1 is the wor-d rim of an Ordin; automobilewhoel,and 2 a band secured to tlie Wood rin: and forming the metal riinto which the pneumatic tire 3 Specification of Letters Patent.

. is secured in any manner suitable to the forni of tire used. This rim2 is of such la width wardly through notches G-iii the edges of the bentend 7 to hook over or embrace the arins gagerneiit with the toward theother. At the third point Where 10, provided with a notch 11. to receivea loop wardly-exteiiding pins '14 on the bands, the slots permitting aslight movement of the bands as they" are tightened by' the levers orset-screws. ln each band is provided a series of countersuiik Openings l'to receive screw-bolts 16, the heads of which lie within thecountersinks in the inner face of the band, and on the projecting cn'dof each of these l' olts is turned a nuD 17, firmly held within aninclosing loop or stirrup 18, vhich loops forni means to which the endsoi' the chains 19 are attached,y said chains being thus adjustablysecured at each end to the bands 4..

Thecentral portion oi' the chain, which extends across the face or tread ofthe s tire, is formed straight or with parallel edges, i so that as thetire is fiattf .l bythe wright at 5, each hook being provided with aset-'screwc 8 at its end extending therethrough into en'- arm to forceone segment the segments ineet the adjacent ends are eacl1 provided withan inwardly-extending end or;l arm 9 to one of which is pivoted ahand-lever vals with slotted openings 13 to receive in- The chains 1.9are llorined, as shown iii Fig.

that a space is left at each side of the tire for two detachablesecuringbands` 4, made in v `three segments and clamped upon the outerface of the rirn by providing one end of each.. segment with an arin orend .5, turned inrini, andj'two of the segments arefprovidedv f' eachwith an iiiwardlyxteiidiiig hook orf' 12, pivoted to the arm 3 on theother segment. l

transversely of the tire with their edges in IOS . 35 thelr opposlteends being secured by adjustits coming ofi?, s litting, tearing, orexploding,

and the armor eing formed of entirely separate and independent chainsdoes not hinder the tire from yielding freely and forms a roughenedtraction treadto prevent the wheel from slippin or skidding.

To prevent the c ains from wearing the tire and/also to insurethe tireagainst becoming punctured by a spike or other sharp instrur11/ent whichmight be forced through or be- /t een the chains, a strip oi leather 2Oor other suitable material is laid on the tread of the tire, and to thisstrip are secured transverse flexible metal plates 21 upon its outersurface beneath the chains in any suitable manner, as by spurs 22,formed on the ends ofthe plates and pressed through and clenched downupon the strip.

In Figs. 4, 5, and 6 I have shown modiiied means for securin thearmor-chains in place, in Fig. 4 the meta rim 23 being anged at 24 orbent outward at one side of the tire and provided with a series ofopenings in which the endsl of the chains are directly secured,

ing-screws to a band 25, made of sheet metal in the form of achannel-bar, the heads of the screws lying within .the channel, and tohold this band from slipping laterally from the tire said tire is formedwith aslightly-upturned edge 26, engaging the outer edge of the band.

Fig. 5 shows a tire which is provided with .laterally-extending flanges27, by means of which 1t is secured to the rim, the armorchalns and saidtire vbeing secured to the rim -by the detachable bands 28, which areformed of sheet metal folded to form channelbands, each having alaterallyprojecting iiange 29 to extend inward over the flanges of thetire and engage the same, the ends -of the `chains being secured to theadjusting-screws, the heads of which lie in the channels of the bands.The metal rim is provided with u turned edges 26 to engage and prevent te bands .from slip ing from the rim.

In Fig. 6 is s own a construction in which the armor-chains are secureddirectly to the wheel-rim 30, (shown in plan view in Fig. 7,) which isprovided near one edge with a series of holes 31 to receive the adjusting-screws for securing one end of the chains to the rim and at itsopposite side is provided with a series of slots 32, extending inwardfrom its edge, and a series of holes 33, one opposite the inner end ofeach slot, for the reception of adjustinghooks 34, substituted for thescrews, and adapted to be slipped into the slots and their upturned endsengaged with the holes 33. To prevent the hooks from becoming disengagedfrom their holes, a thin band 35 is secured to the outer surface of. therim adjacent to the hooks after they are in place, and this band isprevented from slipping laterally from the rim by providing the samewith pins 36 to .engage openings 37 in the-rim.

lIt 1s proposed to clamp each of the diHer- Y ent forms ofsecuring-bands to the rim by providing each band with the link 12 andlever l0, (shown in Fig. 1;) but, if desired, these bands may be made inone piece instead of in segments, as shown in said figure. Y

Having thus fully described my invention, what I claim isl.The'combination with a tire and a rim of greater width than that portionof the tire which engages said rim, of a securing-band engaging theouter surface of the rim at .one side of the tire, means on the ends ofsaid band for drawing said ends toward each other to clamp the band tothe rim, a series of chains extending transversely across the tire andnforming an armor therefor, and means for securing the ends of the chainsto said band.

2. The combination of a tire having laterally-extending"ianges, awheel-rim, bands engaging the outer surface of the rim and each providedwith a laterall -extending iange to engage the flanges on t 1e tire andhold the same to the rim, means on the ends of the bands for drawing theends toward each other to clamp the bands to the rim, a tiredrawing saidends toward each other to clamp the band about the rim, adjustable meansfor securing each of said chains to said band, and means forpreventingthe said band from slipping laterally from the rim.

4. The combination with a tire and a wheel-rim to which the tire issecured, of'an armor for the tire, a securing-band to engage the outersurface of the rim adjacent to the tire and made in two or more parts,an arm formed on one end of one part of the band, a hook on the adjacentend of the other part to embrace said arm, a set-screw carried by theAhook and engaging the arm to force the ends IOO vIO

band to which the armor is attached adapted to engage the outer surfaceof the rim at one side of the tire7 laterally-bent arms on the ends ofsaid band, a lever pivotally attached to one of said arms and providedwith a notch in one side at a distance from its pivot, and a looppivotally attached to the arm on the adjacent end ofthe band and adaptedto engage the notch in the lever When the same is'passed through saidloop.

6. The combination with a tire and a Wheel-rim to which the tire isadapted to .be secured, of an armor consisting of independent chainsextending transversely ofthe tire with their edges 'in contact,securing-bands adapted to engage the outer surface of the rim at eachside ofthe tire and each provided With a series of holes7 means on saidbands for drawing the ends of each toward each other to clamp the bandsabout the rim, adjustingscrews engaging the holes in the bands, stirrupsattached to the ends of the chains, and nuts secured in said stirrupsand engaging the screws.

7. The combination with a tire and a wheel-rim to which the tire isadapted to be secured, of a flexible strip on the tread of the tire, aseries of independent flexible plates secured to said strip, a series ofindependent ilat chains extending transversely of the tire in en gagcment with said plates7 and means for adjustably and detachably securing theends of the chains to the Wheel-rim to form an armor for the tire andhold the strip With its plates in place.

8. The combination With a pneumatic tire, of a Wheel-rim of greaterWidth than the base of the tire which is adapted to be secured theretoand provided with longitudinal slots and notches in its edges, an armorconsisting of independent chains formed of' links Woven Hat and eachhaving a central portion with parallel edges and tapering end portions,adjustingscrews secured to the ends of said chains, securing-bandsengaging the outer surface of the rirnrat each side of the tire and eachprovided with a series of holes to receive the adjusting-screws,inwardlyextending arms on the ends of the bands extending through thenotches in the riin, a lever pivoted to one of said arms on each bandand provided With a notch in its side, a loop pivoted to the adjacentarm on each band to engage the notch in the lever, and pins on the bandsto engage the slots in the rim.

In testimony whereof I affix my signature in presence of t'Wo Witnesses.
